如何在vtk中删除演员？

Question

For example, if i have a cube

(this part of code is from the vtk python example)

import vtk

# create a rendering window and renderer
ren = vtk.vtkRenderer()
renWin = vtk.vtkRenderWindow()
renWin.AddRenderer(ren)

# create a renderwindowinteractor
iren = vtk.vtkRenderWindowInteractor()
iren.SetRenderWindow(renWin)

# create cube
cube = vtk.vtkCubeSource()

# mapper
cubeMapper = vtk.vtkPolyDataMapper()
cubeMapper.SetInput(cube.GetOutput())

# actor
cubeActor = vtk.vtkActor()
cubeActor.SetMapper(cubeMapper)

# assign actor to the renderer
ren.AddActor(cubeActor)

# enable user interface interactor
iren.Initialize()
renWin.Render()
iren.Start()

How can i delete this cube actor and add another one? (This has to be done in order)

Answer 1

Did you tried

ren.RemoveActor(cubeActor);

?

And after that, you simply add another actor

ren.AddActor(anotherActor);
